DEVICE FOR ATTACHING BUTTONS TO FABRICS.

SPECIFICATION forming part of Letters Patent No. 329,336, dated October 2'7, 1885.

Application filed June 7, 1884. Serial No. 134,186.

To all whom, it may concern.-

Be it known that I, IRVING G. PLATT, of WVaterbury, New Haven county, State of Connecticut, a citizen of the United States, have invented a new and useful Improvement in Devices for Attaching Buttons to Fabrics; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying sheet of drawings, forming part of this specification.

This invention relates to an improvement in devices for attaching buttons to fabrics by means of metal rivets; and the invention consists in a button-fastening device constructed in the manner and for the purpose hereinafter particularly shown, described, and claimed.

In the accompanying sheet of drawings, Figure 1 is a longitudinal section of cylinder, button, fabric, and anvil with plunger and rivet in elevation Fig. 2, a cross -section showing the button attached to the garment by the upset rivet; Fig. 3, a plan or top view of same.

Similar letters of reference indicate like parts in the several figures.

This invention relates particularly to devices designed to upset or clinch the end of sharp-pointed fastening contrivances, which rivet the button to the fabric.

The advantage derived from the use of a sharp-pointed rivet as a fastener is the readiness with which such a rivet can be thrust through the fabric or other substance to which it is desired to fix a button; but while this sharp-pointed feature is advantageous in this respect its sharp point renders it somewhat difficult to upset or head over, so as to form the necessary holding-head of the rivet-that is to say, it may, perhaps, not be difficult to merely fold over the sharpened end of such a fastener, but the mere folding over is not sufficient to make the folded end strong enough to answer the purpose, and symmetrical enough to produce a finished appearance, all of which are requisite in a properly-constructed buttonfastener. To arrive at the desired result, I construct a cylinder, A, through which, axially, is made a guideway, a. The undersurface of the cylinderAis formed so as to correspond with the surface of the face of the button B.

(No model.)

Through the guideway a, and snugly fitting therein, is passed a plunger, 1), the lower end of this plunger being recessed, as at 0. An anvil, D, is neXt provided with any suitable means on its face for holding the head d of the pointed rivet 6.

Now, when my device is constructed substantially in the manner hereinbefore described its operation is as follows: The anvil D, with the rivet e vertically placed thereon, is in readiness for the fabric f,which is placed over the point of the rivet e. The button B is next placed so that the point and shank of the rivet, after penetrating the fabric, will pass through the shell of the button and protrude beyond the face of the same. This forcing of the rivet through the fabric may be accomplished by the action of the cylinder A, (or, if preferred, the anvil can be made to perform the same office,) which, descending upon the face of the button, forces the button and the fabric beneath it downward until the rivet shall protrude, as before stated, and when so protruded its sharpened point is received within the guideway a, and at the same instant the plunger b descends with force and curls over the sharpened end of the rivet,and, since the point of the rivet is confined within the recess 0 of the plunger and a portion of the shankof the rivet within the confined space of the guideway, the sharpened end of the rivet is not only doubled over, as before stated, but it is compelled to take the convex shape of the recess a in the plunger, and at the same time the cylindrical shape of the walls of the guideway a, so that the end of the rivet is not only upset, but it is, also, by the same operation, formed into a comparatively-solid and symmetrically-shaped head, which will confine the button to the fabric, as is shown in Fig. 2. The lower end of the cylinder A is recessed, as before stated, as at 9, so that it may receive the configuration of the surface of the face of the button when it rests upon the same and prevent the marring of the button.

It is obvious that the device hereinbcfore described may be attached to a lever to be worked by hand or treadle, or it may be detached from such 5 or the cylinder may be in verted and placed beneath the anvil; or the anvil. may be movable and the cylinder or plunger or cylinder and plunger stationary.

Having now described my invention, what I I 5 claim as new and desire to secure by Letters Patent 1 v IRVING G. PLATT.
